CURTAIN-FASTENER.

Specification of Letters Patent.

Patented Nov. i9, 1918.

Application filed March 10, 1917. Serial N o. 153,818.

To all 107mm t may concern:

Be it known that I, EDMUND S. CHURCH, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Curtain-Fasteners, of which the following is a full, clear, and exact description.

The invention relates to curtain fasteners, such as are used on automobiles.

The object of the invention is to provide an improved fastener whereby the curtain will be positively locked on the stud and which permits convenient release of the curtain by linger pressure applied in removing' the curtain from the fastener.

A further object of the invention is to provide an improved curtain fastener which is simple in construction, is adapted to securely hold the curtain, and can be produced at a low cost.

The invention consists in the several novel features hereinafter set forth and more particularly deiined by claims at the conclusion hereof.

In the drawings: Figure l is a side elevation of the improved fastener, a support and curtain being shown in section, and showing the manner of manipulating the fastener to release the curtain. Fig. 2 is a face view. Fig. 3 is a face view of the hollow stud and its base. Fig. 4 is an inner face view of the curtain showing the washer secured thereto and adapted to fit around the hollow stud. Fig. 5 is a horizontal section on an enlarged scale. Fig. 6 is a section taken on line 6-6 of Fig. 5.

The invention is shown as applied to a suitable support 7 to hold a curtain 8. The improved fastener comprises a hollow stud having a rounded or convex outer end 10 and .formed with an integral hollow base ll provided with holes for screws l2 whereby the stud may be rigidly secured to the support 7. The stud 9 and base l1 are preferably formed of sheet metal and a back plate 14 is secured in the hollow base 1l to close the back of the latter and to provide a support for the latch as hereinafter set forth. Plate 14 fits into the base l1 and is rigidly secured therein by annular flanges l5 which extend around the screws 12 and backwardly from the front-wall of the base and have their ends riveted to the back-plate 14 to fix said plate in the base.

the curtain on A latch 2O is pivotally connected by a pin 2l to an ear or lug 22 formed on the backplate 14. This ear or lug is struck up from the back plate which is formed of sheet metal. Latch 20 is rigid in itself and disposed in the hollow stud 9 and is extended through a transverse slot 23 formed in the curved terminal l0 of the hollow stud and is formed with a stop-portion 24 normally disposed to project outwardly or upwardly from the periphery of the stud to prevent the curtain from being withdrawn. A spring 25 is coiled around pin 21 and interposed between the latch and the back plate 14 to'normally hold the latch in operative position. The outer edge of the latch is serrated or ribbed, as at 26, so that it can be easily gripped or moved by finger pressure appliedto overcome the force of spring25 and it is also formed so that when the latch is shifted inwardly7 the stop-portion 24 will be disposed within the stud or so that it will not project beyond its periphery and will leave the stud clear for withdrawal of the socket on the curtain. The curtain 7 is formed with an opening 28 for the stud to pass therethrough and this opening is usually reinforced by washers 29 and 30 which are clamped to the curtain by tongues 32 on washer 29 which extend through holes in the washers and are clenched on the inner side of the' inner washer 80. These washers are perforated so they will pass around and form a metallic socket for the hollow stud.

In operation, the projecting portion 24 of latch 2O will act to positively prevent the withdrawal of the curtain from the stud, because' outward pressure of the curtain will not tend to move the latch against the force of the spring'. To release the curtain, it is only necessary to shift the portion projecting from the slot 23 transversely in slot 23 so that the opening in the washers on the curtain will clear the locking portion 24. This can be conveniently done by the thumb of the hand applied at the same time that the curtain is grasped for withdrawal as shown in Fig. l. By thumb pressure on the latch, the curtain will be released so that it can be easily withdrawn from the stud. To place the stud, it is only necessary to force it over the stud. The washers on the curtain, in being forced ba ckwardly, will force the latch transversely against the force of the spring so the curtain and washers can peripheral and end ein pass onto the stud, and as soon as the curtain has passed to the rear of the locking portion :2i of the latch7 the spring will torce the latch into operative position and the curtain will be securely held on the stud.

rlhe invention exemplifies a curtain tastener in which a latch mounted in a hollow stud and inovable transverselyy ina slot in the end or' the stud, will serve to hold the curtain and which can be easily manipulated to release the curtain. Also one, in which the resiliency7 of a latch is not relied upon to hold the curtain.7 because the outward pressure oit the curtain against the locking portion oie the latch has no tendency to nieve the latch transversebVT to the stud. The device is formed mainly of sheet inetal part-s which can be produced at a low cost and is eiiicient in operation,

rlhe invention is not to be understood as restricted to the details set forth, since these may be modified within the scope or the appended claiins.,v without departing from the spirit an( scope of the invention.

Having thns described the invention, what l claiin as new an'l lesire to secure by Letters Patent7 is:

l. ln a curtain il-aetener7 the combination of a hollow stud having `an integrah thin.,l wall provided with n'ieans whereby it niav be secured to a support and having a slot in its outer end, a lnovable latch having` a portion projecting through said slot and from the periphery or the stud to'hold a curtain on the stud the latch being movable in the slot to release t1 e curtain7 and nieans in the hollow stud to sustain the inner end of the latch.

ln a curain fastener, the conibination or a hollow stud comprising an annular peripheral and end wall provided with fr reedoee ineans whereby it inay be secured to a support and having a transverse slot at its outer end and a latch having' its inner end sustained in the hollow stud and its outer end projecting through said slot and troni the stud ynear the outer end thereof, to hold a part on the stud, the outer end of the latch beinginovable in the slot to release said part.

ln a curtain fastener, the combination ot a hollow stud provided with nieans wherebv it may be secured to a support and havi ine; a transverse slot at its outer end, and a latch having its inner end sustained in the hollow stud and having its outer` end conforming generally to the shape of the outer end oit the stud and provided with a portion extending through the slot and projecting roin 'the stud to hold a curtain on the stud, the outer end of the latch being movable in the slot. to release the curtain.

4:. T he combination of a hollow stud having nieans wherebg7 it Inav be secured to a support, kand having a transverse slot at its outer end, a latch in the stud and having a portion projecting through said slot to hold a curtain on the stud and whereby the latch niav be shifted to release the curtain, and a back plate secured to the bach ot' the stud and having ineans Jfor supporting said latch.

T he combination of a hollow stud provided with a base having means whereby it may be secured to a support, and having a transverse slot at its outer end, a latch in the stud and having! a portion projecting through said slot to hold a. curtain on the stud and whereby the latch inay be shifted to release the curtain, and back-plate secured to the baci; ot nieans for supporting said latch.
